I was thinking of modifying the exhaust on the XR8 when I eventually get it. I made a few enquires and a cats back 3" system seems to be the go but I can not understand how a single 3" system compared to the dual system it already has can produce better performance and sound. In the "old" days any V8 with a single exhaust system was changed for twin pipes. I know I use to do it myself. Any IDEAS?

Our sainless steel system is twin 2,5 and over the axle 3 inch then twin 2.5 out the rear.Makes around 10 kw+ at the wheels and sounds tough
